Waves relying on physical movement of materials like those of sound or those sen in water require a medium. Electromagnetic (Light, radio, microwaves, etc.) and gravitational waves can travel without a medium in the vacuum of space. This allows us to see the stars and planets. Scientists originally felt there was an "ether" a mysterious material filling space two allow this transmission but this was eventually disproved.
No. Electromagnetic waves need nothing.
Radiation doesnt need a medium because it travels through space
Yes, mechanical waves do need a medium in order to travel. Other waves, such as light, do not (thus they can travel through space).
No. Electromagnetic waves travel through vacuum ( ie space where there is nothing)
Waves need not require medium to travel through. Only Mechanical waves like sound waves require medium to travel through. Electromagnetic waves travel in vaccum like light waves. Some waves transmitted in a medium due to disturbances in the medium .
The biggest difference is that mechanical waves require a medium to travel through and electromagnetic waves do not.
No, only surface and mechanical waves need a medium, compressional waves can travel through space. (Such as light from the Sun).I think light (EM) waves are the only ones that can travel through a vacuum. Sound waves require a medium.
no
Sound waves need a medium to travel through - the medium may be solid, liquid, or gaseous. Electromagnetic waves (including light) can also travel through empty space.
Mechanical waves need a medium substance to travel through. Electromagnetic do not.
Mechanical waves need a medium to travel in
Electromagnetic waves don't need anything to travel. This kind of waves does not need a medium to move through, therefore they can even travel through outer space.
Sound wave do not travel through vaccum as it need medium to travel.
